Range them, far easier. If you prefer melee, and wanna "live" there, bring a d hally and attack over the table. Bring 1 Glarial Ammy, 1 Rope, 1 P pot (fail safe) a few lobs. 40-50 nats 0 fires (you'll get plenty to alc with) and 1 chisel. If you're living there, you wont be keeping gems, so just cut them, bolt tip them, and get something out of them.
